Ask your agent for a company’s technology detections, with first and last seen dates for each. ### Different sources, different evidence. PredictLeads attaches job openings and web pages to its detections, BuiltWith lists detections by page, and Findymail groups tools by category. ### See how sure each detection is. PredictLeads gives each detection a score from 0.25 to 1, a source count, and first and last seen dates. ## Questions ### Do I need a Wappalyzer account? No. Your agent pays from your TaskFuel balance, so there is nothing else to sign up for. ### What does a technology lookup cost? Our PredictLeads lookup cost $0.04 on 2 November 2026. Wappalyzer’s Pro plan is $250 a month with 5,000 technology lookups, as published that day. Your agent shows the price for your own request before it pays. ### Is it the same data as Wappalyzer? No. Each source runs its own detection, so the technologies and dates differ. ### Does Wappalyzer have a free tier? A free Wappalyzer account includes 50 lookups a month, and API access needs a plan. TaskFuel suits agents that need each result as data. ## Related tool guides - [Compare BuiltWith alternatives for a site’s technology](https://taskfuel.ai/tools/builtwith-alternative/) - [Add company details to the technology lookup](https://taskfuel.ai/tools/company-enrichment/) - [Inspect a URL’s structured metadata](https://taskfuel.ai/tools/url-metadata/) ## Reference - [Read this guide on the website](https://taskfuel.ai/tools/wappalyzer-alternative/). - [Browse providers and capabilities](https://taskfuel.ai/catalog/). - [Pricing](https://taskfuel.ai/pricing/). - [Agent instructions](https://taskfuel.ai/llms.txt).
